The RizomUV Bridge provides the user with an easy to use UI which makes transferring objects and UV maps between Blender and RizomUV as simple as clicking a button.  The addon includes many user-configurable settings so the user can set up the bridge to best suit their workflow. These settings are all saved in the preferences file and will be remembered between Blender sessions.
